Reynolds number of fluid flowing in Pipe

Go Reynolds Number = (Fluid Velocity*Pipe Diameter*Fluid Density)/Absolute Fluid Viscosity

Flow Rate

Go Volume Flow Rate = Pipe Cross Sectional Area*Fluid Average Velocity

Volume Flow Rate

Go Volume Flow Rate = Mass Flow Rate/Material Density

Mass Flow Rate

Go Mass Flow Rate = Material Density*Volume Flow Rate

Length of Pipe Formula

Pipe Length = (2*Pipe Diameter*Head Loss due to Friction*[g])/(Friction Factor*Fluid Average Velocity^2)
L_p = (2*D*H_f*[g])/(f*V_avg^2)

Why is it called head loss?

The pressure head is due to the static pressure, the internal molecular motion of a fluid that exerts a force on its container. Resistance head (or friction head or Head Loss) is due to the frictional forces acting against a fluid's motion by the container.

How to Calculate Length of Pipe?

Length of Pipe calculator uses Pipe Length = (2*Pipe Diameter*Head Loss due to Friction*[g])/(Friction Factor*Fluid Average Velocity^2) to calculate the Pipe Length, The Length of Pipe formula is defined as the length of the pipe through which the fluid flows.
